Python and Windows Services Question

[Phoe6]

Hello,

This is a windows services question. The following script which is a
windows service was supposed to something ( download wallpaper and set
the desktopwallpaper) at 16:45 my time here. The service is running,
but the supposed action did not take place. Does anyone who is aware
of win32 apis point me what I am doing wrong here: http://paste.pocoo.org/show/106428/

I don't know much about Win32 Services. So I took the example snippet
from Mark Hammond's book on Python Windows programming.

Any help appreciated.

Thanks,
Senthil
